Higher dietary fibre intake is associated with increased skeletal muscle mass and strength in adults aged 40 years and older.

Higher dietary fibre intakes are associated with a lower BM and enhanced body composition, characterized by a reduction in fat mass and an increase in lean mass. Higher dietary fibre intakes were also associated with improvements in glucose homeostasis and skeletal muscle strength. Increasing dietary fibre intake may be a viable strategy to prevent age-associated declines in skeletal muscle mass.
